Guide To QuietCool Whole House Fans


A whole house fan is a ventilation cooling system that uses less energy than a traditional air conditioner. This energy-efficient system works by pulling cool, outdoor air into your home and out your attic vents. This process enacts Thermal Mass Cooling, keeping your home cooler, longer.


QuietCool should be used anytime the outside air temperature is lower than the inside temperature. This is key for the principle of Thermal Mass Cooling to work.

What do many people do when they come home after work and it is really hot outside but cool outside? They open their windows instead of turning on their A/C so they can draw in that cool air. These open windows create a cross breeze and cool the home through thermal mass cooling.

The “passive” cross breeze described above becomes an “active” breeze for QuietCool homeowners and this is the key to thermal mass cooling. Passive breezes within a home will eventually cool the ambient air to a comfortable level but will not move enough air to cool the mass within the home.

When correctly sized, a QuietCool system will fully exchange the entire air volume of a home 15-20 times per hour, or about one full air exchange every 3 to 4 minutes. The “active” breeze is how QuietCool thrives.

Mass “cooling” results because the QuietCool system is removing stale, hot air and replacing it with fresh cool air. All of this is occurring at a high rate of speed and volume, 15-20 times per hour, which is why it works so much better than a simple cracked window.

Therefore, instead of recycling hot, stale ambient air through a closed-loop air conditioning system, the QuietCool system is exchanging hot, stale ambient air with fresh, cool outside air, through an open-loop whole house ventilation system… and at a fraction of the cost of running an air conditioner.

A “cool mass” home does not reheat as much or as quickly as a “hot mass” home. Within a day or two of installing a QuietCool system, homeowners are amazed when they come home after work and their house is still cool from the night before!

The reason the home remained cool was that the mass of the home had been cooled by a QuietCool system and thus did not reheat as rapidly as it typically would.

QuietCool is truly a revolutionary product that allows people to save money by turning their A/C off and turning their QuietCool system on!


Since it is normally cooler in the evening and mornings, this would be the best time to turn on a whole house fan. Homeowners simply have to open a few windows and the whole house fan will cool and ventilate the entire home. Whole house fans can exchange the entire air in a home every 3-4 minutes or 15-20 time per hour. When running the system for several hours, all the hot air will be pulled out of the mass in the home. This process is called Thermal Mass Cooling. The hot air is pulled out and then vented through the attic. This allows the home to stay cooler the next day because the entirety of the home was ridden from heat. The home will feel significantly fresher because of this.


QuietCool can save homeowners huge amounts of money off their A/C related cooling costs. Even if the homeowner does not have A/C, they can still stay cool for pennies an hour. QuietCool is a High Volume Exhaust System equivalent to 50 - 100 typical bath fans per 10 - 20 typical kitchen range hoods.

QuietCool can exhaust cooking odors, smoke, shower steam, pet dander and airborne germs or allergens within a few minutes.

QuietCool customers can expect their system to pay itself back in energy savings, typically within 2 - 3 years.

That means that QuietCool is one of the fastest payback systems of all Green Energy Systems on the market today!

10 - 15 year warranty!
